Kernel Recommended Defaults

Kernel Recommended Defaults

[Peter Moscatt]

I am about to compile and install my first kernel and
want to make sure I have things pretty well set before
I create the image.

Is there guides available where they show recommended
defaults - especially in the Network arena ?

Before configuring the kernel (IE doing make xconfig or make menuconfig, or
just editing .config) do a make oldconfig. That will load the defaults in
all parts, otherwise I'd suggest reading the help that's included with the
given options in the configuration program (IE hit ? in make menuconfig or
click on the *fuzzy memory* help button in make xconfig).

Hope that helps

1. although the initrd is a nice hack, I generally
avoid all that and compile all the requirements of
the root file system into the kernel -

2. everything else, I generally compile as modular.
this is extremely helpful in troubleshooting, e.g.
you can load/unload drivers without a reboot.

3. It doesn't hurt to have modules compiled for
cards you don't need, since they will not be
loaded. However, you want to avoid the opposite
scenario - not having the driver you need.

4. the defaults are usually sane, but look at
each and every one the first time you do a
kernel config.

5. DO NOT simply blow away your old kernel -
you will be sorry if you do. leave the old kernel
intact as a fallback, and make the necessary
edits to lilo, grub or whatever boot manager
you are using.
